To all whom it may concern:

Beit known math-ALEXANDER TURKING- TON, a citizen of the United States, residing at Lafayette, in the county T of Tippecanoe and State of-Indiana, have invented certain new and useful Improvements in Pile-Fabric Looms, of which the following, in connection with the accompanying drawings, is a specification. T i I The invention to be hereinafter described relates to pile-fabric looms, andmore particutricate figures.

larly to that class'of such looms whereby tufts of yarn are introduced and passed between the warp-threads with the ends of the tufts projecting upon the surface of the fabric to produce the pile eifect. In looms of this general character as heretofore commonly employed the mechanical construction and operations have been such as to render the loom cumbersome andslowin'its movements, and

to introduce thet'uft-yarns according to a preconceived patternthe plan commonly practiced was to wind the desired colored yarns on long spools or beams in the order in which they would appear in any row of tuft-yarns across the fabric, a number of such spools or beams being carried by a long and heavy chain, which was moved to present the spools or beams successively over the Warp-yarns,at whichpoint the-spool or beam was detached from the chain and carried by a transferrer to pass the tuftyarns through the Warp. Such old form of construction necessitated a very long chain, and if the pattern formed by the tuft-yarns was extended beyond very simple patterns the length of tuft-yarn chains be came so great asito present a serious problem in their handling, and, moreover, they occupied so much room and were so heavy as to be practically useless for the formation of in- It is the object of my invention to simplify the construction of tuft-pile-fabric looms, to make them more compact, to provide means whereby the figure or pattern produced by the tuft-yarns may be varied as desired under the controlofpattern mechanism without the employment of the cumbersome and heavy tuft-yarn-carrying chains, and to providefor the accomplishment of other results of an improvedcha-racter over the prior devices, all as will hereinafter: more fully appear.

senting the tuft-yarns in any desired order for the formation of a pattern on the face of the fabric and also in the general combinations, parts, and devices, all as will be hereinafter fully described and then be definitely pointed out in the claims.

. In the drawings, Figure 1 is aside view of a loom embodying my invention, some of the parts being omitted and a part of the frame being broken away to betterdisclose the pat tern-controlled devices for determining the relative position of the tuft-yarn holders, a part of said devices being in section. Fig. 1 is a detail of the actuating means for the tuftyarn carrier. Fig. 2 is a front view of the loom shown in Fig. 1. Fig. 3 is an enlarged sectional detail transversely of the tuft-yarn carrier, as on line 0c 00, Fig. 2. Fig. 4 is a section on the line y y, Fig. 3, showing one of the tuft-yarn holders, some of the parts being omitted to better disclose the construction of the holder. Fig. 5 is an enlarged sectional detail similar to Fig. 3, showing the tuft-yarncarrier shaft and the disposition of the pawls for engaging the tuft-yarn holders with the shaft and disengaging them therefrom. Fig. 6 is a sectional detail, on an enlarged scale, of part of one of the tuft-yarn tubes and connected parts. Figs. 7, 8, and 9 are sectional details of different modifications of means for supporting the tuft-yarn in the holders. Figs. 10, ll, 12, 13, 14, and 15 are details, respectively, of the tuft-yarn carrier, showing it in the various positions it occupies during the operation of inserting the tuft-yarns around the threads of the fabric. Fig. 16 is a diagrammatic view of one of the tuft-yarn holdwarp-threads when the tuft-yarn carrier has been shogged. Fig. 17 is a like diagrammatic view showing the relative positions of the end of a tuft-yarn tube and the lower comb during the insertion of the tuft-yarn around a warp-thread. Fig. 18 is a like diagrammatic View showing by full lines the position assumed by the tuft-yarn holder and its tuftyarn tube with respect to the Warp-threads after the return shog'ging movement of the by passing around the said threads and preers, showingits position with respect to the carrier. Fig. 19 is a section on line z a, Fig. 1, of one side of the loom. Fig. is a sectional detail, on an enlarged scale, of the pattern-controlled devices for determining the positions of the tuft-yarn holders with respect to each other. Fig. 21 is a perspective view, on an enlarged scale, of one end of the gripper which holds the end of the .tuft-yarnsduring the return movement of the tuft-yarn carrier. Fig. 22 is a sectional detail of the comb for giving a lateral movement to the warpthreads on the line 2" 2', Fig. 1. Fig. 23 is a section on line y y of Fig. 22. Figs. 24 to 31 are diagrammatic details showing the various movements that are imparted to the tuft-yarn-carrier arms during an entire cycle of movements for the insertion of a tuft-yarn and the withdrawal of the carrier to its normal position, a single cam being illustrated as the operating means to simplify the illustration. Fig. 32 is a detail view showing the divided holder and means for securing its parts together.

The loom-frame A, the warp-beams A A the take-up rollA and their adjunctive parts are and may be of any usual or preferred form and construction, and to more clearly disclose the present embodiment of my invention and to prevent unnecessary complication in the illustrations and descriptions I have purposely omitted the shedding mechanism, the lay, the shuttlemotions, the tuft-yarn-cutting mechanism, and their adjunctive parts, as these form no part of my present invention and may be of any usual or preferred type.

Mounted on each side of the loom-frame in appropriate position to give the necessary movements to the tuft-yarn carrier for the insertion of the tuft-yarns are the tuft-yarncarrier arms A, which attheir ends loosely carry, so as to be rotated therein, the tuftyarn carrier, (designated as a whole by A The said tuft-yarn-carrierarms A in the present embodiment of my invention are designated to have a rising, falling, and endwise movement, and as one of the many supporting means for said arms to permit such movements I have shown pins or rollers A projecting from the loom-frame, which engage slots A in said arms, the end Walls of the slots A serving as stops for the endwise movement of said arms; but it is to be distinctly understood that I do not regard my invention as limited in this respect, as any means may be employed for the support of said arms so long as they are permitted to have the described movements. As one of the means for imparting the described movements to the arms A and consequently the desired movements to the tuft-yarn carrier A for the insertion of the tuft-yarns and the withdrawal of the carrier from the inserting position, I have provided the free end of the arms with oppositely-projecting pins A A", which bear upon the two cams A A, mounted upon the cross-shaft A which is given appropriate rotary motion from any moving part ofthe loom, as through the shaft A connected to the cross-shaft A by the bevel-gears A A and driven from the cam-shaft A cams A and A are so shaped that they impart to the carrier-arms A and consequently the tuft-yarn carrier, movement to lower the carrier to place the tuft-yarn tubes between the warp-threads, then give to the carrier a shogging movement to carry the end of the tubes across the warp-threads, then a rising and forward movement to carry the end of the tuft-yarns above the plane of the warp and close to the fell, and then reverse the movement of the tuft-yarn carrier to return it to its original position above the warpthreads and out of the path of the lay as the latter heats up, all as will be hereinafter more fully described; but while I have shown cams for securing this cycle of movements it is to be understood that my invention is not limited in this respect, and any form of mechanical devices that will impart the necessary movements may be employed.

Mounted in the ends of the carrier-arms A A is the carrier-shaft B, which is free to ro-- tate in said arms, said shaft having connected thereto a pinion B, adapted to engage a rack B carried by an actuator E the said actuator deriving the requisite motion to give rotation to the shaft B in one direction by virtue of the ratchet-and-pawl connection 12 at between the pinion and shaft through a lever B pivoted at B and havinga roll B engaging the cam B carried by the cam-shaft A; While 1 deem this a desirable form of actuating mechanism for the carrier-shaft B, it is only one of the many forms of such devices that will suggest themselves to one skilled in the art, and my invention is not limited thereto, as any of the desired forms of such mechanism may be employed so long as they give to the shaft 13 two rotations on each beat up of the lay.

The carrier-shaft B has formed therein longitudinally thereof a series of grooves B (see Figs. 3, 4, and 5,) and loosely mounted on said shaft are a series of tuft-yarn holders 0, the number of said holders being dependent upon the number of tuft-yarns desired to be placed in the fabric in the transverse rows of tufts, and each of said holders is provided with means for supporting a series of tuftyarns, five of such tuft-yarns-being shown in each holder in the present illustration of my invention; but any desired number may be employed, and each of the tuft-yarns carried by the holders may diifer in color or quality, or both, from the other yarns, as desired. The various tuft-yarns carried by the tuftyarn holders may be supported in any desired manner-as, for instance, such yarn may be wound upon small spools 0, Figs. 3, 7, and 9, and carried by a removable frame 0, Fig. 3, which when desired may be removed from the holder and replenished, or such spools a may be carried by arms 0 Fig. 7, having one The said as shown in Fig. 8.

mit the insertion and removal of the spools, as shown by Fig. 9,.tw of said bars or rods c being preferably carried by a hinged cover 0' on the holder, as will be more fully eX-L plained, so that uponturning back the cover I the spool cmay bereadily removed and re-% placed, orthe tuft-yarns may be simply coiledf in chambers or receptacles C of the holder 0, In any event I preferably divide the holder into a number of sup porting sections or chambers, as C each for the reception and support of one character or color of tuft-yarn, and while I have shown the holder in its present formas a closed casing it is evident, of course, that the character of the holder may be varied, and, indeed,

be a skeleton frame, which is sufficiently obi vious without multiplyingthe illustrations.

PreferablyI provide a cover 0' for each of 1 the sections .or chambers in the holder and hinge said cover, as at 0 so as to turn outward, a spring 0. being provided to cause the cover to turn outward, as shown by dotted lines, 3,-on its hinge when a trip or lock 0 is released from its holding-catch 0 Figs. 3, 6, 7, 8, and 9, and projecting outward from each of the sections or chambers C of the i I holder is a tuft-yarn tube C One side of each of the tuft-yarn tubes is provided with a slot 0 Fig. 6, and pivoted on thetuft-yarnholder at c", Fig. 6, is a trip-arm c, normally resting against the tuft-yarn within the tube,but

which when said tuft-yarn breaks or becomes exhausted turns outward through the slot O? and by its shorter end 0 disengages the trip a from the holding-catch 0 thereby permitting the cover C to swing outward and indicate either that the tuft-"yarn in that particuj lar section or chamber is exhausted orbroken and needs replenishing or repairs. Thusthe cover which I preferably employ for each section or chamber acts as an indicator as to the condition of the tuft-yarn carried by the. holder, and although this. constitutes one simple and effective form of indicator it is evidentthat any device that will notify the attendant whena tuft-yarn has become exhausted or broken mightbe employed.

As hereinbefore specifically described, the tuft-yarn carrier is composed of a plurality of tuft-yarn holders, each separate from the a the i end of the tuft-yarn extending beyond the end of the tube.

In the production of tuft-yarn fabrics it is desirable that the tuftyarns be introduced in rows transversely of the warps in varying combinations to produce a figure effect upon the face of the resultant fabric, and I have therefore provided means which, under the control of any desirable pat-ternmechanism, may produce any combination in qualities, characters, or colors of tuft-yarn supported in the series of tuftyarn holders, said means in general state ment within the scope of my invention comprising detachable connections between the tuft-yarn holders and the carrier-shaft, said eachinsertion of a tuft-yarn, as will now be described.

Mounted on each of the tuft-yarn. holders so as to be capable of movement to engage with or disengage from the longitudinal grooves 13 in the carrier-shaft B are a series of connecting devices or pawls 1), Figs. 3 and 5, each having an operating projection 19, by which the connecting devices or pawls b may be moved to withdraw them from engagement with the longitudinal slots in the carrier-shat t B, said pawls being normally held in engagement with said slots by spring-fingers b pivoted at 12 Figs. 3 and 5, the free end b of each finger I) being extended to underlie the next adjacent finger at a point beyond its pivot 53, from which construction it will be seen that should any one of the projections 19 be moved to disengage its pawl from the longitudinal slot in the carrier shaft 13 its connected fingers I) will also be moved on its pivot if, thereby lifting by its free end the next adjacent finger and connected pawl, and so on around the entire series of pawls, so that a disengaging movement of any one of the projections b will cause all the pawls to be disengaged from the carrier-shaft, and the tuft-yarn holder on which these pawls are mounted will then be disconnected from the carrier'shaft and remain at rest. In order to provide against too-free movement of the holders on the shaft, as by sliding thereon, I have found it desirable to provide each tuft-yarn holder with a light tension-spring b and adjustingscrew b, Fig. 3. Each of the operating arms or projections 19 has 2. turned or bent end b and the said operating arms or projections b on any one carrier are of diiferent lengths, so that in the rotation of the carrier with the shaft the longest operating-arm would meet with and be arrested by a projection that the next shorter and remaining arms would pass, and the next shorter operating arm or projectionwould meet and be arrested by a projection that all the other shorter arms would pass, and soon around the series, and onthe arrest of any one of the arms of the series all the paWls or connecting devices would be disengaged from the carrier-shaft B and the holder carrying said arm would remain at rest.

It will be evident from the above-described construction that if while all the tuft-yarn holders are revolving with the shaft an abut ment or projection be moved into position to engage all the longest operating-arms 1) throughout the series of tuft-yarn holders then all of said holders will be disconnected from the shaft and'be held at rest, with their longest arm against such projection or abut ment and in no other position, and such position I will hereinafter designate as the prede= termined or normal position, it being the position to which all of the holders are retu rn ed after having inserted tufts of yarn. It will also be evident that if said abutment or proj ection above referred to be removed from engagement with the longest arms of the holders the holders will become connected to the shaft and revolve with it, and if while revolving a series of pins be projected into the path of movement of any of the arms or projections then such arms or projections will engage such pins and the corresponding holders be arrested in position according to the particu- ,.lar arm or projection engaged, as will now be described.

Mounted on and extended across the loomframe in proximity to the path of movement of the operating arms or projections b are-a pair of guide-bars D, Figs. 1, 9, and 20, provided with. perforations for a series of pins 01 d said pins being connected by a rocking link (1 having a pin-and-slot connection, as shown, with said pins (1 (1, whereby as the pattern-pinsd are projected the pins (1 are retracted, and vice versa. The series of pins d, extending across the loom-frame, are connected by bell-crank levers d with the tail cords or connections d of any desired form of pattern mechanism, as a jacquard, and

said connectors or tail-cords are joined to the bell-crank levers d at different points in the length of the arm of said bell-crank, whereby upward movement of the tail-cords or connectors will serve to movethe bellcrank through a greater or less angle, according to thedistance of its connection from the end pivot (i of the bell-crank,'and consequently the pins (1' will be projected more or less, according to the tail-cord that may be lifted. When the parts are in position as indicated in Fig. 20, with the pins (1 unacted upon by the jacquard or other pattern device, they are retracted, so that the ends of all'the operating arms-or projections 19 will pass the ends ofsaid pins d without engagement, and at this time the pins d are fully projected, so that the ends thereof are in position to be struck by the longest of the operating-arms b'to thereby stop all of the tuft-yarn holders in a predetermined or normal position. With the tuft-yarn holders thus in predetermined or normal position, it being desired to change the relation of the sections or chambers of the holders to bring different tuft-yarns into the atternin (1 correspondin to any P P a holder the pin is projected to its extreme forward position, and if the longest arm of any holder is to be engaged by the pattern pin corresponding to that holder said pin is projected to its shortest forward position, and so on for all the, pins and holders across the loom, and the pins d being all simultaneously withdrawn from engagement with the longest operating-arms b by movement of the patternpins (1 the whole series of holders on the carrier-shaft will turn with said shaft until any holder having turned sufficiently to bring the proper tuft-yarn in posi tion next to the warp-threads the operatingarm of said holder will engage its pattern-pin d and arrest further movement of the holder. The shaft B thus makes a complete revolution in direction of the arrow, Fig. l, on the indication for a pattern of tuft-yarns being formed by the jacquard, the timing for such movement of the shaft being produced by the actuator B from the necessary shape of cam E This complete revolution of the shaft B is necessary on the formation of each combination or row of tufts to be inserted, because the call of the pattern may require a holder to stop with the longest arm I) against a pattern-pin, and since the normal or predetermined position of all the holders is with the longest arms 6 in engagement with the pins (1 the particular holder referred to may have to make almost a complete rotation with the shaft prior to meeting its patternpin, the direction of movement being as indicated by arrow in Fig. 1. It will be understood, of course, that there will be as many pattern-pins d as there are tuft-yarn holders 0 on the carrier-shaft B, one pin controlling the movement of one holder through the pattern or jacquard. The tuft-yarn holders being thus arrested in their movement with the shaft and having the proper pattern or combination of tuft-yarns formed next the warp and ready to be inserted between the same, the actuator B ceases to act to further turn the shaft B in the direction of the arrow, Fig. 1, and both the shaft and the holders remain for the time relatively fixed, while the actuator B descends, merely turning the pinion B on the shaft by virtue of the ratchet-and-pawl engagement therebetween. The to ft-yarns are now ready to be placed between the warp, as will presently appear, and the carrier is thereafter returned to its upper position above the warp to permit the beat-up, at which time the pattern-pins d are retracted under the action of the jacquard and the positioningpins cl are projected,ready to engage the longest operating-arms b of the holders, which by virtue of the revolution of the carriershaft, to which the holders are rotatively connectedby the pawls b, are carried arounduntil such engagement takes place, whereupon the holders become rotatably detached from the carrier-shaft and remain at rest in'their j cat-ed in Figs. 2 and 19, one of said cams, as

they might, if desired, be

predeterminedor normal position, as before.

While I have thus described one of the preferred embodiments of my invention as the pattern-pins d and positioning-pins d, together with the operating-arms b to be engagedas stated, I do not wish to be understood as limiting myinvention in this respect,-as the number, character, and disposition ofthese'parts maybe varied.

lhe tuft-yarns having been disposed on the carrier in desired relation for the formation of a row of tufts, it'nowbecomes necessary to from'the sides of the arms A, as hereinbefore described, and although one cam might be employed for giving the entire series of movements, as I have indicated diagram matically inFigs. 24 to 31 for the sake of clear-v ness and simplicity, yet in practice I have foundit desirable to employ the two cams, one on each side of each of the arms A as indi- A, being designed to give the rising-andfalling movement to t-he carrier A and take the weight thereof, while the cam A is designed with a contour-or cam surface to give an upward or backward movement to the arms and carrier in the direction of the length of said arms. The starting or normal position of the actuating-cams A Whilethe carrier is in its upper position, at which time the pattern-pins d and positioning-pins (1 act upon the operating-arms b, is represented in Fig. 24, wherein the high part of the cam bears upon the pin or roll A and by depressing and holding this end of the arms A depressed raisesand maintains raised the carrier A of the arrowthe carrier A is gradually low cred, with the tuft-yarn tubes, into the warps,

, as represented in Fig. 10, which shows the 1 carrier to havebeen' moved from its dotted to its full line position. The tuft-yarn being now between the warp-threads, it is desirable to give a shogging movement to the carrier AL-that is, to pull back on one of the arms A, while the other arm A moves slightly forward -and this I accomplish by providi ngthe cams on opposite sides of the loom with shogging depressions m m and disposingone cam slightly in advance of the other with respect to the shogging depressions, which serve to permit the arms A A to move different dis- As the cams movein the direction tances forward in the direction of'the arrow, as shown in Fig. 25, the result being that the various tuft-yarn holders and the tuft-yarn tn bes below the warp-threads take a slightlydiagonal position with respect thereto, as indicated in Fig. 16, so that as the carrier rises slightly under the action of a riser m of the cams the ends of the tuft-yarn tubes will he carried above the warp-threads onthe side thereof opposite to which they enteredthe warp, as indicated in Fig. 11. A continuation of the surface 1% then permits the arms A toslide forward from their position indicated in Figs. 11 and 26, so as to carry the ends of the tuft-yarn tubes close to the tell of the cloth, as indicated in Fig. 12, at which point the grippers, to be hereinafter described, operate to engage the end of the tuftyarns. The tuft-yarns having thus been entered between the warps and held by the grippers, to be described, the carrier A is to be returned to its normal upper position, or that position from which it is started, the first movement to secure't-his return being indicated in Figs. 13 and 28, wherein by the latter is shown the cam-surface m engaging the forward end of the roll or pin on the end of the arm At and drawing said arms backward the extent of the slots A in said arms, and by virtue of the disposition of the cams and such cam-surfaces m at opposite sides of the-loom the carrier-A is given its return shoggirrg movement and lowered slightly by the-contour m as indicated in Fig. 29, so as to carry the end of the tuft-yarn tubes below the warp-threads and in a position, as'indicated in Fig. 18 by full lines, so that the tuft-yarn tubes will not engage the warp-threads as the carrier is raised, which raising movement takes place gradually, as shown in Figs. 30 and 31 and indicated from the dotted to the full line position of the carriera in Fig. 15. In this raised or normal position the arms'A whichsupport th'e tuft-yarn carrier A will be in the position again as'indicated in Fig. 24, the disposition of the cam-surfaces 0n the operating-cams for the arms A being such as to maintain said arms in the position indicated, with the carrier raised and with the arms retracted, with the pins or rolls A at the forward end of the slot A as indicated in Fig. 24, and when the carrier A is lowered into the warpat its forward "position it will be noticed that the pin A is at the upper end of the slot A and these slots A in the opposite arms may be so disposed as to maintain the carrier A in its shogged position while introducing tufts ofyarn.

While I have thus described with reference to Figs. 24 to 31, inclusive, a singlecam on each side of the loom-frame for operating the carrier-arms A for the sake of simplicity and clearness,itis to be understood, of con rse,that I may form this cam in two parts, as I have above indicated and shown in Fig. 2, for instance, wherein part A serves to hold the arms with the carrier in raised position, while will be substantially the same as that indi-' cated in Figs. 24 and 31.

While I have found cams desirable to perform the movement hereinbefore described to the tuft-yarn carrier A it is to be understood that other means may be employed within the scope of my invention.

In order to insure the proper crossing of the tuft-yarn tubes around the warp-thread, which may be secured solely by the shogging movement given to the tuft-yarn carrier, I have provided a comb below the Warp-threads which will serve to move the warp-threads slightly to one side as the tuft-yarn tubes are shogged and rise from under the said warpthreads,and as one embodiment of the construction of said comb I mount upon a crossbar F,'beneath thewarp-threads, a series of pins f, projecting upward therefrom, said cross-bar preferably traveling in. guides, as F, secured to the sides of theloom-frame, as

more clearly indicated in Figs. 22 and 23.,

Mounted on a shaft F which derives motion from the cam-shaft A through any suitable operating connections, is a cam F upon which a projecting toe F of the comb rests, as clearly indicated in Fig. 1, whereby the comb may be given a rising-and-falling movement as the said cam F is turned by the shaft. Secured upon the guides F are camshoes F which after the pins fof the comb have engaged the warp-threads w, as indicated in Fig. 22, move the said comb endwise, thereby carrying, the warp-threads in front of the tuft-yarn tubes slightly to one side, as indicated by the diagram in Fig. 17, to thereby furtherinsure that the tuft-yarns as they rise between the threads will be laid across the same on the upward movement.

Pivotally mounted on the cross-shaft G, journaled in the loom-frame, are a pair of rocker-arms G, one end of which, as G bears upon the periphery of a cam G secured on the shafts F whereby the rockerarms G are given rocking movement as the cams G are actuated by the shafts F Mounted upon the ends of the rocker-arms G and extending therebetween is a gripper g, preferably consisting of a continuous strip having teeth g, said gripper being disposed above the warp-threads, as indicated in Fig. 1, a spring 9 normally causing the rockerarms G to bear upon the periphery of the cams G I Mounted upon the loom-frame, as

indicated in Fig. 2, is a cam G, which, bearing against the side of the rocker-arms G, causes said rocker-arms and the gripper carried thereby to be moved slightly crosswise of the loom after the teeth of the gripper have engaged the warp-threads in a manner similar to the movement of the comb F, so that said gripper thereby serves to further insure the lateral movement of the warp-threads to secure certainty in the placement of the tuftyarns around said threads. When the tuftyarns have been carried into the position as indicated in Fig. 12, with the ends of the yarns close to the fell, the gripper is given a further forward movement to engage the end of the tuft-yarns projecting fromthe tuftyarn tubes, such movement being permitted by reason of the change in the shedding of the warp, which occurs about this time. If found desirable, the cam G may be provided with a contour which will permit a slight raising ofthe gripper from engagement with the warp-threads after the tuft-yarns have assumed the position of Fig. 12 and to at once return the gripper to engage such tuftyarns and hold them as the tuft-yarn carrier A is returned to its normal position.

I do not wish to be understood, of course, as limiting my invention by the necessary employment of the comb F and the laterallymoving grippers for supporting the warpthreads to enable the tuft-yarns to be properly inserted, as these may be dispensed with under some conditions; but I have found such devices to be desirable in this connection. Nor do I intend to limit my invention to the particular construction and operation of the comb and grippers, as they might be modified.

I have indicated inthe drawings by the lines to w the condition of the warp-threads when the shed is open for the reception of the weft or filling, and I have indicated also by w the completed fabric as it is wound upon the cloth-beam A but the details of shedding mechanism and other parts not forming essential features of my invention have, as hereinbefore stated, been omitted for the sake of clearness.

It may sometimes happen that the tuftyarn holder (J may become injured or some of its parts become inoperative or defective, in which event it is desirable that such tuftyarn holder may be readily removed from the carrier-shaft and replaced by a new holder without disturbing the relation of the re maining holders on the carrier-shaft, and to this end I form each ofthe holders 0 in two parts, as indicated-inFig. 32, the said parts of the holder being detachably joined together by spring-clips 70, secured to one part of the holder and engaging suitable projections on the other part of the holder, as will be obvious. Of course any form of detachable connecting means for the two parts of the holder might be employed, and I do not restrict myself in this respect, but merely show the above-described construction of one means for securing the parts of the holder together upon the shaft.

By the mechanism hereinbefore described it will-be noticed that I have provided a tuft- ICC pilefabric loom in which the tuft-yarns are all carried by a suitable carrier, and which tuft-yarns may, under the call of pattern mechanism, have their position changed with relation to each other, so as to vary the patternof the tuft-yarns in any row of tufts, and it will alsobe noticed that after each insertion of a row of tufts the tuft-yarn holders are all returned to a predetermined or normal position with respect to each other as, for instance, that all of the sections or chambers throughout the series of holders I, containing a white yarn shall be in line with each other across the loom so that when the pattern or jacquard mechanism operates to indicate a pattern for tuft-yarns all of the tuft-yarn holders will start to move from the same predetermined or normal position.

I believe myself to be the first to provide in a tuft-pile-fabricyloom a carrier for the tuft-yarns, said tuft-yarns being controlled as to their relation with eachother on the carrier by a pattern or jacquard mechanism, and I desire to claim such construction broadly.

Having thus described my invent-ion, what I claim, and desire to secure by Letters Patent, is- I I I 1.
